Application filed January 29, 1916. Serial No. 75,104.

To all whom it may concern:

Be it known that I, CLARENCE D. BAR- TRAN, a citizen of the UnitedStates of America, residing at Laurel, in the county of Jones and Stateof Mississippi, have invented certain new and useful Improvements inDevices for Holding Covers or Chest-Lids, of which the following is aspecification, reference being had therein to the accompanying drawings.1

This invention relates to a device for holding a cover or chest lid inan elevated set position without danger of the cover o r hd accidentallyswinging to a closed position. Another object of this invention is theproduction of a slide having a plurality of notches formed therein so asto fit over a stud for the purpose of retaining a cover, lid, or stormwindow in an open or elevated position, while a plurality of trips areprovided for directing the slide past the stud without permitting thestud to pass into the notches when the slide is being moved so as topermit the cover, lid, or window to be moved to a closed or loweredposition.

A still further object of this invention 1s the production of a luralityof dogs which are mounted upon't e slide in such a manner that after theslide passes the stud to such an extent as to prevent the movement ofthe stud into a notch the stud will so swing the dogs as to cause thesame to clear the notches, whereby upon the next movement of the slidein the opposite direction when the cover or lid is being moved to anopen position the notches will be unobstructed so as to permit the. studto pass into a selected one.

.With these and other objects in view this invention consists of certainnovel combinations, constructions, and arrangements of parts as will behereinafter fully described and claimed.

In the accompanying drawing:

Figure 1 is a side elevation of the device, showing the same mountedupon a box, illustrating how the same is used for retaining the lid inan elevated position.

Fig. 2 is a section taken on the line 22 of Fig. 1, looking in thedirection of the arrow.

Fig. 3 is a fragmentary side elevation of a portion of the device,'illustratlng the same in detail in connection with the operation of thedogs. 3

Fig. 1 is a fragmentary top plan view of the free end of the slide,showing the dogs mounted thereon.

Fig. 5 is a fragmentary side elevation of a portion of the slide.

Referring to the accompanying drawing by numerals it will be seen thatthe device comprises an elongated slide 1 having a longitudinallyextending slot 2 formed therein. This slide 1 is further provided with aplurality of notches 3 com1nunicating with the upper portions of theslot 2, as shown clearly in Fig. 5, and each of the notches 3 isprovided with a side 5 which extends at a right angle to the top edge ofthe slot and an outwardly-extending slanting side 6 with respect to thetop edge of the slot. This slide is pivotally secured by means oftherivet 7 to the forwardly extending end 8 of the bracket 9 which issecured by means of the screws or other securing means 10 to the lid 11of the box body 12.

The plate 13 is secured by means of the screws or other securing members14 to the box body 12 and has extending from its outer surface the stud15 having a head 16 formed thereon. This stud 15 extends through theslot 2 formed in the slide 1 and, therefore, the slide will pass over orby the stud 15. Therefore, it will be seen that when the lid 11 is movedfrom a closed position as indicated in dotted lines in Fig. 1 to an openposition as indicated in full lines in Fig. 1, the slide will be drawnover the stud 15 until the stud moves into one of the notches 3 formedin the slide by the dropping of the free end of the slide suflicientlyto permit this action. Since the normal tendency of the lid 11 is tofall to a closed position it will urge the slide 1 in one direction soas to cause the straight side 5 of the particular notch in which thestud 15 is resting to bear against the stud, thus holding the slideagainst accidental movement so as to retain the lid 11 in an elevated oropen position. It is obvious that the stud may be easily removed from anotch for by a continued movement of the lid toward a further openposition the stud willride upon the slanting side of the notch, thuscausing the stud to move from the notch to the next notch or to aposition where the slide may be prepared for movement for permitting thelid to be moved to a closed position.

The dogs17 areelongated and are pivotally secured by means of the rivets18 130 the slide 1 at a distance above the slot 2 and danger ofaccidental movement. It will be seen that these dogs 17 are cut at theirlower "portion to provide the pockets 19 thereby forming the trippingends 20. hen theli d is in'a closed position the dogs will be in theposition indicated in dotted lines in Fig.

' 1. At this time it will be seen thatthe upperends of these dogs willbe raised high enough to cause the pockets 19 of the dogs '17 to bepositioned above the notches 3. As the slide moves so "as to cause thesame to pass over the stud 15 the studwill try again to passthe dogspositioned on the slide. Of course, it is obvious that the slide may beprovided with any desired number of dogs.

After passing the first notch the stud will engage the lower trippingend of the first dog so asto swingthe upper tripping-endof the dogdownwardly as disclosed in full linesin Fig.3 in connection with'theupper dog. The continued movement of the slide will cause the stud tomove iiitothe next adjacent lower notch and after the movement ofthelidinan opendirection is stopped the lid will be retained in a set openposition. Then it is desired to close the lid the lid is first movedtoward an open position so as to cause the stud to move from thenotchwhich it has just been occupying by' the riding ofthe slide thereon. Assoon as'the stud engages the lower tripping end 20 of the lower dog itwill swing the upper end of the dog downwardly so as to causethe innerportion of thepocket 19 of this dogtoextend' below the planeof the upperportion ofthe slot formed in the slide 1. Therefore, the movement of theslide as the lid is moved to a closed position will cause the studtomove within the pocket of the lowerdog past the notch in the slideadjacent which the lower dog is pivoted. Therefore, after the stud isdirected past the lower notch it will engage the upper tripping end'ofthe lower dog so asto swing this'dog upwardly at its upper end, therebyagain causing the notch in the slideto be open and unobstructed. By afurth'er movement of the slide the stud will come into engagement withthe inner portion of the pocket of the next higher dog which at thistime will be'eXtending almost transverselyacross the path'of travel ofthe stud. The stud, however, being engaged by the central portions ofthe highest dog within the pocket '19 will swing the dog to such aposition as to permit the stud to pass the notch of this do until uponthe engagement of the stud with theupper tripping end of this upper dogthe dog will be swung high enough to disengage the stud and permit thelid to be moved to its final closed posithe slide past the stud willcause the stud to trip the -dogs whereby upon the reelosing of the lidthe dogs will be swung so as to guard-thenotches and thus permittheslide to pass thestud withoutany possibility of the stud passing intoone ofth'e notches formed in the *slide. I

It is, of course, obvious that this device may be used inconnec'tion'with any hinged or swinging object for'retainlingthesame in anopenposition and, therefore, it is not intended-to restrict-theconstruc'tionof thisiinvention to the specific form and arrangement-asherein disclosed but to include all such "forms of the invention asproperly come within the scope of the device "as claimed.
